Couldn't resist the cool price, these step-up step-down transformers have many uses indeed. I ordered 20 of these because first needed a few good strong vacumm tube drivers for a tesla coil project. Secondly, these also have good 10 to 50 khz oscillation capabilities due too the simple feedback design. Also makes a good audio isolator in high-q amplifier projects. I put two in parallel for higher current projects and two or more in series for greater voltage output requirements. These also work just fine as coupler transformers in multivibrator oscillator/driver projects too.

I tried using NPN transistor but it didn't work. I then used a Mosfet and it worked. I powered it with a 7.2v battery.
